Total ion current chromatograms of (A) a solvent extract of a P. americana parasitized by A. compressa and (B) a SPME sample of the secretion of an A. compressa larva. Although the relative amounts of compounds showed a broad variation, the chromatogram can be considered typical. The peaks of minor components are not always visible due to the magnification used. Peak numbers correspond to the numbers in Table 1. h, hydrocarbon; IS, internal standard; 1, (R)-(-)-mellein; 8, micromolide (Table S1 and Fig. S1).
